Deflector Died

Super bummed that my Deflector died after it was mistakenly plugged into live 9VDC. Heard a tiny pop then crickets. I’m guessing the eeprom is fried. I will swap it. Pedalpcb should update their Deflector to the new Afterneath v3!!!

It's a series diode so it should have half-wave rectified the AC and produced a DC voltage... it certainly shouldn't have failed.

The sole purpose of the diode is to protect the circuit against reverse polarity, and that's exactly what AC is half of the time.


I think we need more clarification about what this was plugged into and what it actually does / doesn't do.

No sound whatsoever wouldn't be caused by the EEPROM.

It certainly doesn't eliminate the EEPROM as defective, but a bad EEPROM wouldn't affect the dry signal path.


Does the LED light?

Do you have a dry/clean signal when Mix is turned all the way down?

If you have a DMM, measure the voltage on the input and output of the 3.3V regulator.

Is this just a ploy for a v3 upgrade? :ROFLMAO:

Accidentally feeding 9VDC into something expecting a lower/internal regulated voltage can definitely take out sensitive parts fast. The tiny pop followed by silence is unfortunately a classic symptom. The EEPROM could be toast, but on the Deflector there’s also a chance the voltage regulator or the DSP itself took the hit.

These pedals normally run on 9VDC. I'm thinking there may have been some static somewhere and when I connected it, BAM! Transient spike took out the eeprom.

If you were to ask my wife, then yes, this is most certainly a ploy to upgrade to the v3 😂😂
I've had one in my Reverb cart for a while.
All seriousness though, I'd love to get it working again.

Always sucks when a pedal dies. Haven't had anything go wrong when using the proper 9V DC power though.

Repeating Robert's questions from above, as they would help clarify what's wrong:

Even it the EEPROM died, you'd still have dry signal with the mix turned down, if that's dead too something else (also) could be wrong.

It’s says you mistakenly plugged it into 9V DC. I guess that’s where the confusion is.

The LED went out with the pop

That wouldn't be a factor in why the pedal died. It's likely something moved around inside while pulling the pedal off the board, which landed on a trace somewhere, and when power was applied voltage was introduced to the shor

Nothing moved around. It’s a super nice, tidy build. It’s passing signal when bypassed just not when it’s on. All the voltages are good. I’m certain it was a static discharge that fried the FV-1. It wouldn’t take much. I’m chalking it up as a loss and have since bought a v3 Afterneath and an expression pedal. I didn’t have much time or money in the Deflector. Letting it go.
